The utility model has the advantages of simple structure, big torque, high revolution, high efficiency and long lifetime and is widely applicable for industrial uses and civil uses.
Description
Affiliated technical field
The utility model relates to a kind of motor of Electric Traction, is that a kind of power consumption is low, can realize high pulling torque, the disc-type electric motor of high revolution.
Background technology
At present, existing motor normally has the casing of a tubular, and stator is arranged in the casing, and rotor is arranged in the stator, and this design makes Motor torque improve the difficulty that becomes.Such motor power consumption is high, and efficient is low, and material usage is big, and motor is made complicated.The disc-type electric motor that also has patent applied for, as the patent No. 200410018810.6, this patent motor is made complicated, and brush is easy to wear, and power of motor is difficult for improving.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides a kind of rotor bank purpose disc-type electric motor that increases.The utility model has well solved the problem of present motor, has gathered every advantage of cartridge type motor and present disc type electric machine, and motor performance is greatly improved.
The technical scheme that its technical problem that solves the utility model adopts is: in electric machine casing, the axle that has large end face is installed on wherein the installation fore bearing that is linked in sequence from left to right, preceding rotor, field frame assembly, back rotor, nut, rear bearing.Preceding rotor connects near large end face and constitutes.Being connected of large end face and preceding rotor by the screw rod connection that is fixed as one.During installation, at first on axle, be inserted in a preceding rotor, and fix with screw rod and large end face, square with the axis with rotor before guaranteeing, then, on axle, be inserted in field frame assembly.Field frame assembly is by axle sleeve, the stator bearing, and stator bracket, electromagnet is formed.Its installation process is as follows, tightly is inserted in two stator bearings on axle sleeve, is inserted in stator bracket again, and the electromagnetism iron rule is fixed on the stator bracket.After field frame assembly being enclosed within on the axle, again the back rotor is inserted in axle, use fixed by nut again, compress the parts of being loaded onto.Fixing locked preceding rotor and back rotor with key and axle, prevent its rotation.After the two ends of axle install fore bearing and rear bearing, the motor case of packing into, and with screw motor cover is tightened.Wherein internal rotor is equipped with magnet.Axle sleeve has two effects on electric machine structure, one it make before rotor and back rotor remain square with the axisly, and can not radially wobble.Two it and two stator bearings and stator bracket tightly connect as one, and so just can guarantee that field frame assembly is square with the axis all the time, and can not radially wobble.
The method that increases the stator number is: take off the back rotor, load onto the double polarizing keys rotor, refill a field frame assembly, the back rotor is also loaded onto, and got final product with fixed by nut.The structure of electromagnet is, the both sides that are connected cylinder with two porose baffle plates on skeleton, are installed iron core again and just made electromagnet with enamelled wire as skeleton.
